My invention relates to andhas for a purpose the provision of a simple,substantial and inexpensive machine particularlyadapted although notnecessarily, for use in removing the rind from bacon, and by which theremoval of the rind can be effected with the utmost ease and dispatch,thus greatly facilijtating the preparation of the bacon for use andeliminating the skillful labor required in present methods of manuallycutting or otherwise removing the rind; from'the bacon. I will describeonly one formof rind removing machine embodying'my' invention-and willthen point out thenovel features thereof .in claims; V

In the accompanying drawing,

Fig. 1 isa view showing in plan partly a broken away, one form of skinremoving machine embodying my invention. 7 Q Fig. 2 is a verticalsectional view taken onthe line 22 of Fig. 1, and' Fig. 3 is a view inend elevation of themachine shown inthe preceding figures. 7 Referringspecifically to the drawing in similar partslin each of theseveralviews, my invention in its present embodiment comprises a frame Fpreferably constructed of sheet metal to providea rectangular base 10having upstanding flanges 11 along itsside edges. The base 10 isprovided with openings through which fastening members 12 are adapted tobe extended to secure the frame to a horizontal support such as a tableor bench 13. The base 10 and flangesllcO- operate to provide a troughadapted to freely receive a slab or side of bacon therein; andjour'naled in the flanges 11- to span the latter horizontally, is ashaft 14 on whichthe rind of a piece of bacon insertedin the troughbelow the shaft is adapted to bewound.

Theshaft 14 may be angular'in cross secton such as square for example asillustrated, to provide edges for preventing slipping of the bacon rindduring winding there of on the shaft, or may be provided with 'pros'jections or teeth 15 at intervals along its length adapted to ventslipping of'thelatteron the shaft.

The shaft is adaptedto be rotated in a which similar referencecharacters designate penetrate the rind to precounter'clockwisedirection as viewed 2 either by means of power or by a crank 16 fixed toa shaft 17 journaled in theflanges 511; the shaft 17 having also fixedfthereto a .M.

pinion gear 18 meshing with a relatively large gear 19 for increasing:the power d veloped at the crank. j ,7 7

As the bacon rind is being wound on the shaft 14, the'bacon is caused totraverse .a path" different from that of the rind so as to v separatethe latter from the bacon by "a'stripping or tearing action. To this endI pro- 'vide an abutment designated generally atA for directing orguiding the bacon tangentially from the shaft, and advanced between theflanges 11 asits rind is wound on the shaft. In the present instancethis abutment comprises a round bar 20 terminating at its ends in rightangularly disposed parallele'x tensions 21 slidably mounted in. U shapedbrackets22 fixed to the flanges 11, to support the 'b'ar 20substantially] at the level ofv and 1 parallel Withthe shaft'14for'movement hori- 'zontally towards and away from the shaft. 51;:

The abutmentis normally urgedtowards the shaft 14 by means of coilsprings 23sur roundingthe extensions 21 and bearingat' one end againstpins 24 extending diametrically through the extensions, and at theirother ends against one of the arms 25 brackets. The movement of theabutment towards the shaft is limited to a position in which the bar 20clearsthe-teeth 1 5, by means of other pins 26 whibh-are adapted toengage v the .arms 25 ,ofthe extensions, H y

' Apiece of bacon when inserted between the shaft 14 and the base 10 isadapted to be urged upwardly towards the shaft and to this end I providea platform 27 on fwhich the bacon is adapted to rest, pivotallymount- 7,7

ed at one end on the base 10, by means of pins .28-extending throughears ,29 and 30 on the platfor'mand baserespectively. The freeend of theplatform is normally urged upwardly .by means ofcoil'springs 31interposedbe tweenthe platform and base 10 and receiving projections 82-and'38 formedonthe platform 7 and base respectively, to prevent lateraldisplacement ofthe-springsl The yieldability e V of the platformprovides for sides or slabs 3 ingly maintain the rod in engagement withof bacon of different thicknesses, and insures that the bacon will beheld up to the shaft 1 L regardless of the thickness of the bacon.

The operation of the machine is as follows: Let it be assumed that it isdesired to remove the rind from a side of bacon. The

. bacon is first slit under the rind from one end by a suitablev knifeto form a flap of rind.

The platform 27 is now depressed and the end of the bacon insertedbetween the platform and the shaft 1d, which the free end of thepreviously formed flap of rind is passed upwardly between the-shaftlaand the rod 20 and then wrapped about the shaft, The crank 16 is nowoperated-torotate'the shaft 14: in a counter-clockwise direction asvielwedin. 2. As the forward end' of the .bacon from which the flap ofrind has been removed, extends in advance of the bar 20 it .will beclear that upon continued rotation of the shaft l thfl rind will bewound'nponthe shaft, whereas winding of the bacon on the shaft will beprevented and'the bacon dierect ed or'guided by the rod'20 tangentiallyfrom the shaft so as to be] fed or, advanced overv the platform 27,"thus stripping or tearing the rind from the bacon; As the coil of rindon the shaft la increases in diameter, the springs 23' permit'the rod 20to be forced away from the shaft, and operate to yielda means. fordirecting or guiding apiece of bacon for movement along a predeterminedpath, and the shaft 14 a means towhich the bacon rind is attachable, forcausing the rind to traverse a different path from the bacon in a mannerto effect stripping ortearing -of therind from the bacon. i

Although I have herein shown and described only one form of rindremoving machine embodying my invention, it. is tobe understood thatvarious changes and modifications may be made therein without departingfrom the spirit of the invention and the spirit and scope of theappended claims. I T

I claim:

A rind removing machine comprising means to which the rind of a pieceof bacon is attachable, means for mounting the first means for rotarymovement-to efiect' winding j ofthe bacon rind thereon, means fordirect-' ing the-bacon tangentially from the" first means as, the baconrind iswound on the latter, to thereby efie'ct stripping of the rindfrom the bacon, and means for urging the last means against the rindwound on the first, means for the purpose described.

2. A rind removing machine comprising means to which the rind of a pieceof bacon is attachable, means for mounting the first means for rotarymovement to efiect winding of the bacon rind thereon, a movable abutmentfor directing the bacon tangentially from the first means as the baconrind is wound on. thelatter, to thereby efi'ect stripping of the rindfrom the bacon, and means for urging the abutment against the rind woundon the first means yet rendering the abutmentfree to yield as the coilof bacon rind increases in size.

3i A' rind removing machine comprising means to. whichthe rind of apiece of bacon is attachable, means for mounting the first meansforrotary movement to effect winding of the bacon rind thereon in coilformation,

means for directing the bacon tangentially from the first means as thebacon rind. is wound on the latter, to thereby elfect stripping of:therind from the bacon, and means for normally urging the bacon bodilytowards the first means, yet yielding as the'coil of bacon rindincreases in size.
